Europa-List: What This Loctite For?

[Troy Maynor <wingnut54@charter.net>]

Hi All, 
I hesitate to bring it up but I'd like to know. I have this 5ml bottle 
of Loctite 648 with only German language on it. I can't remember where I 
used it, or if I have still to use it on something important. There's 
nothing on my punch list other than service bulletin 15 which uses 
Loctite, and that's Loctite 603. Could it be for the elbows on the water 
pump that I had to change out. Just wondering around in the fog....
